Function Specifications - Omron SYSMAC CJ2H-CPU64-EIP Datasheet

*1. "Packets per second" is the number of communications packets that can be processed per second.
*2. Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the data size. Application is
supported between CS/CJ-series PLCs. When connecting to devices from other manufacturers, make sure that the devices support the Large
Forward Open specification.
*3. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.
*4. When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a timeout will temporarily
occur at the other node that was communicating with that port, and it will then recover automatically.
*5. The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using a switching hub that supports IGMP
snooping.

A minimum cycle time can be set.
(0.2 to 32,000 ms; Unit: 0.1 ms)
The minimum cycle time setting can be changed in MONITOR mode. (Unit version 1.1)
The cycle time is monitored.
(0.01 to 40,000 ms; Unit: 0.01 ms)
Instructions with long execution times can be executed over multiple cycles to prevent
fluctuations in the cycle time.
Cyclic Refreshing Cyclic refreshing of Basic I/O Units, Special I/O Units, and CPU Bus Units
Immediate Refreshing I/O refreshing by immediate refreshing instructions
Refreshing by IORF I/O refreshing by IORF instruction
The number of units recognized when the power is turned ON is displayed.
The input response times can be set for Basic I/O Units. The response time can be
increased to reduce the effects of chattering and noise at input contacts. The response
time can be decreased to enable detecting shorter input pulses.
All of the outputs on Basic I/O Units can be turned OFF when an error occurs in RUN or
MONITOR mode.
Alarm information can be read from Basic I/O Units and the number of Units recognized
can be read.
A Special I/O Unit or CPU Bus Unit can be restarted.
I/O words can be automatically allocated to the Basic I/O Units that are connected in the
PLC to start operation automatically without registering Units into I/O tables.
The current unit configuration can be registered in I/O tables to prevent it from being
changed, to reserve words, and to set words.
The first words allocated to a Units on the Racks can be set.
The status of I/O memory can be held when the operating mode is changed or power is
turned ON. The forced-set/reset status can be held when the operating mode is changed
or power is turned ON.
Files (such as program files, data files, and symbol table files) can be stored in Memory
Card, EM File Memory, or Comment Memory.
The user program and Parameter Area can be backed up to an internal flash memory
when they are transferred to the CPU Unit.
Parts of the EM Area can be treated as file memory.
I/O comments can be stored as symbol table files in a Memory Card, EM file memory,
or comment memory.
EM Area can be set as trace memory or EM file memory.
A program file and parameter files can be read from a Memory Card when the power is
turned ON.
The whole user program can be read from a Memory Card to CPU Unit during operation.
Data in I/O memory in the CPU Unit can be written to a Memory Card in CSV/TXT format.
Data in CSV/TXT format in the Memory Card can be read to I/O memory in the CPU Unit.
